Question

How is rayon made?

Answer

Rayon a type of artificial silk Discover in China it is made by the chemical treatment of wood pulp.

Answer

Rayon is made from wood pulp through chemical processes done in factories.

Answer

Rayon is made by the chemical treatment of wood pulp. It is made in the following ways: 1. wood pulp is dissolved into the sodium hydroxide solution which results into a sticky liquid called ' viscose'. 2.this sticky liquid is forced to pass through a metal cylinder with tiny holes called spinneret into the solution of sulphuric acid where silk like thread of rayon is formed. hope that helps!!!

Answer

How is Rayon Made?
Rayon is a versatile and popular fabric known for its softness and draping qualities. It is made from natural cellulose fibers, usually derived from wood pulp. The process of making rayon involves several steps, which are outlined below:

1. Harvesting and Pulping:
- The first step in making rayon involves harvesting wood from trees such as pine, spruce, or beech.
- The wood is then chipped and treated with chemicals to break it down into cellulose.

2. Dissolving the Cellulose:
- The cellulose pulp is then dissolved in a solution of chemicals, such as sodium hydroxide, to create a viscous liquid called viscose.
- This viscose solution is aged for several hours to allow it to mature and develop the desired properties.

3. Spinning the Fiber:
- The viscose solution is then forced through spinnerets, which are like showerheads with small holes, to create long filaments of rayon fiber.
- These filaments are then washed to remove any residual chemicals and dried to form continuous strands of rayon fiber.

4. Drawing and Cutting:
- The rayon fibers are stretched and drawn to align the molecules and improve the strength and durability of the fabric.
- The fibers are then cut to the desired length for further processing.

5. Weaving or Knitting:
- The rayon fibers are spun into yarns and then woven or knitted into fabric.
- The fabric can then be dyed, printed, or finished to achieve different textures and appearances.
Overall, the process of making rayon involves several chemical treatments and mechanical processes to transform natural cellulose into a versatile and luxurious fabric.

Answer

Rayon is made by -

cellulose + sodium hydroxide= alkali cellulose

alkali cellulose + carbon disulphide= orange colour suspension like small fragments of beads

orange colour suspension + sodium hydroxide = viscose solution

viscose solution is then passed through the fine holes of shower head of a spinnerent into an acid bath

viscose solution+
sulphuric acid = cellulose filament=> yarn

then the fibre is stretched ,washed and dried and finally rayon take up package
